Creating a Sys Admin Program

To set the stage:
I'm brand new to C#, and I have been developing with VS 6.0. for about 4 years now, most of which was web development to include VB, VBS, and J++. Now I have been given a new task and I really don't know where to begin. I hope that someone out there can direct me in the right direction.

The situation:
I need to create a small program that runs in the background during the entire time the client is logged in to there system (Windows 9X - 2000). But when ever the client tries to save or download anything, I need this program to take over and record or/and control what is going on.

The plea:
Would any one have any knowledge that could help this, AKA me, slightly intellectually challenged person? If so I would very much appreciate it. Thank you

that´s a hard one if you only did web development before.

afaik windows has "hooks" for everything. download the "windows sdk" docs and the "platform sdk" docs from www.microsoft.com (also available online). there you could find the infos. also visit http://msdn.microsoft.com

some of this is put in the registry. like the default action for clicking on ftp links. but the details are beyond my knowledge

there is also "hook functions" in windows that might do similar tasks. also to be looked up in the windows/platform SDKs.

another hint: try to search google for a search string like "programming windows hook ftp download" or similar.

also for windows system programming using borland delphi, some pages that helped me alot (besides ms.com):
http://www.torry.ru
http://delphi.about.com
http://community.borland.com

Thanks you very much for all your help. At least now I have a route to research. Thank you once again.
